China car app Didi updates safety measures after murder

Didi Chuxing claims to be the world's largest ride-hailing service, with more than 450 million users and 21 million drivers. The driver - a 26-year-old male who abandoned his vehicle and jumped in a river - has since also been found dead, according to the South China Morning Post. The Hitch service has previously faced criticism from users who complain that the app allows drivers to leave comments on their profiles regarding their appearance. Currently drivers are vetted through verification of personal ID, driving licence and vehicle registration certificates as well as background checks. Didi Chuxing counts Apple among its investors and recently received a licence to test self-driving cars in California, a year after it opened a Silicon Valley research lab to develop autonomous driving technology.
